.This'invention relates to door closers and has special reference to improvements in a combined bracket and closure for such.

The principal object of the invention is to provide a more simple construction and assembl of such a device.

- Another object is to produce means for the holding or locking of such an assembly together both for shipping as well as during the time of application of the device to a door.

Other objects and advantages of the invention will appear in the following description thereof.

Referring now to the accompanying drawing, forming part of this application, and wherein like reference characters indicate like parts:

7 Figure 1 is a top plan view of one of the improved door closers.

Figure 2 is a side elevation of same.

Figure 3 is a section on the line 3--3, of Fig- ,.ure 2.

Figure 4 is a rear elevation of the closer.

-In the drawing, the numeral 1 represents the fiat, sheet metal, bracket portion of the device which has formed in the wider and front face thereof the upwardly projecting semi-cylindrically shaped closure portion 2 for reception of the central coiled body-portions of the spring member 3 of the assembly, said closure having an opening I4 at the base thereof for the reception of the hereinafter described loo-p like portion 4 of the coils. The central coiled body portions of the spring member are preferably formed, as clearly illustrated, in two right and left hand coils, slightly spaced and with that portion intermediate of which coils being turned backwardly forming the loop-like portion 4 for direct impingement against the upper face of the bracket portion I. This bracket portion has formed therein any desired number or arrangement of suitable screw holes 5 for fixed engagement with the trim of the door frame, not shown. The opposite arm-like portions of the spring member are indicated at 6 and extend from the other end convolutions of the coils and are spaced materially farther apart than the portions forming the loop 4. The ends of these arms 6 are bent inwardly as at l to form a suitable shaft for the rubber or other roller 8 as clearly shown in dotted lines at 9, and this roller is obviously for impingement against the door, not shown.

Upon either side of the closure portion 2 of the bracket is formed an upstanding lug portion ll! of the bracket, and at the union of such lugs with the bracket is a downwardly struck journal portion II for the reception of the locking pin 12 which is placed transverse the front of the bracket within said journal after the springhas been placed within the closure, thus holding the spring housing and bracket member tightly gether. It will be understood that the spring 5 when thus united is exerting a considerable expansive stress against the pin, thus holding it in; position against accidental dislodgment. lnthis, manner the entire unit becomes exceptionally; convenient in both construction and assembly, as 1Q well as for shipping, and application to a door.

In this latter event, the assembled unit is simply applied to the door trim as by screws or the like with the front edge of the bracket in substantial alignment with the union of the door and trim "15 as a guide to its proper position, and when the, bracket is finally tightened against the trim the roller 8 of the closer'will have sufiiciently im-, pinged the door to have relieved thestress of the arms 6 against the pin I 2 at which time the latter will drop by gravity from its holding position, leaving the assembly freeto function as antici-. pated as an adequate closer for the door. Obviously, if the tightening of the bracket is insufliv cient for this latter purpose, a slight opening of 5 the door will function to free the locking pin, when it will be no longer needed unless at a time when the closer is removed from the door.

It will be noted that the upper inner edge of the lugs I0 is removed at an angle as at [3, which results in these lugs acting as a guide in the return of the arms 6 each time the door is closed 1 to insure their proper registration, and such lugs may be as extensive as desired for such purpose.

Having thus described my invention, what I 35 claim and desire to secure by Letters Patent, is:

1. A door closer comprising a bracket portion, a spring housing extending integrally from said bracket portion, a spring within said housing having arms extending in opposite directions, one of said arms being adapted to bear against a door, and a pin extendible intermediate of said bracket and arm to hold said arm in substantially parallel relation to said bracket when said closer is not functioning as such. 45

2. A door closer comprising a bracket portion,

a semi-cylindrical housing portion extending from said bracket portion, a door closing spring removably installed within said housing portion and having a central coiled body portion, arms extending in opposite directions from said spring body, one of said arms bearing against said bracket and another of said arms adapted to bear against a door, and a removable pin extendible between said bracket and last mentioned arm to hold said arms in substantially the same plane when the door closer is not functioning as such.

3. A door closer comprising an integrally formed spring housing and bracket portion, a door closing spring removably held within said spring housing, and having a central coiled body portion, an arm extending from said spring and adapted to bear against a door, and an automatically releasable locking member extendible between said arm and said bracket for holding said bracket and spring together until assembled in connection With a door.

4. A door closer comprising an integrally formed spring housing and bracket portion, a door closing spring removably held within said spring housing, an arm extending from one of the convolutions of said spring and adapted to bear against a door, and means extendible between said arm and said bracket for holding said arm and bracket in substantially parallel relation While the door closer is not functioning as such.

5. A door closer comprising a bracket attachable to a support adjacent a door, a semi-circular housing extending from said bracket and having an opening therein, an expansive coiled spring installed within said housing and having pairs of arm-like portions extending in opposite directions therefrom, one pair of said arms extending through said opening and bearing against said bracket and the other pair extending free of said bracket and adapted to bear against a door, and means extendible between said latter pair of arms and said bracket for holding said pairs of arms in substantially the same plane when the door closer is not functioning as such.

6. A door closer comprising a bracket portion attachable to a support, a semi-cylindrical housing portion extending from said bracket, a coiled door spring removably held in said housing and having arm-like portions extending in opposite directions therefrom, said housing portion having an opening therethrough for passage of one of said arms therethrough for bearing engagement with said bracket, and the other of said arms extending in the opposite direction adapted for engagement with a door.

'7. A door closer comprising a combination with a mounting device attachable to a vertical support adjacent a door and embodying a substantially fiat body portion, a semi-cylindrically shaped portion pressed upwardly from the central portion of said bracket, a coiled spring body adapted to fit within said semi-cylindrically shaped portion, an arm extending in one direction from one of the convolutions of said coil and adapted to bear against a door, and an arm extending in the opposite direction from another convolution of said coil and bearing against said fiat body portion.

8. A door closer comprising a combination with a mounting device attachable to a vertical support adjacent a door and embodying a substantially flat body portion one edge of which is provided with an upstanding lug at either end, a semi-cylindrically shaped portion extending upwardly from the'central portion of said bracketand having an opening therein, a coiled spring body adapted to fit within said semi-cylindrically shaped portion, a pair of arms extending in one direction from certain convolutions of said coils and between said lugs to hold said arms from spreading during operating of the closer, said arms being adapted to bear against a door, and other arms extending in the opposite direction from certain other convolutions of said coil and through said opening and bearing against said H'IRAM B.
